Introduction
Structural
Health
Monitoring (SHM) is the whole process of the design,
analysis, development and implementation of techniques for the
detection,
localization and estimation of damages,
for monitoring the integrity of structures and machines within the
aeronautic, civil and mechanical engineering infrastructures.
Structural
or modal analysis
is a particular instance of the problem of
estimating the eigenstructure (eigenvalues, and observed components of
eigenvectors) of the state transition matrix of a linear dynamical
system under nonstationary excitation.
Modal analysis
- Stochastic subspace-based modal analysis under nonstationary excitation [ASME01].
- Multi-patch version of stochastic subspace modal analysis under nonstationary excitation [SP02] [JSV02].
- Comparing input/output and output-only modal analyses [JSV06].
- Proving
the convergence of
subspace identification methods under nonstationary
excitation [AC07].
Structural health monitoring
- From stochastic subspace modal
analysis to structural monitoring
